r128gain's Introduction

r128gain

Fast audio loudness scanner & tagger

This project is no longer maintained.

When I first wrote it, there was simply no solution to analyze audio loudness and tag files accordingly on Linux from the ReplayGain v2 or Opus R128 conventions.

Now there are several better maintained alternatives, and I recommend using rsgain instead.

r128gain is a multi platform command line tool to scan your audio files and tag them with loudness metadata (ReplayGain v2 or Opus R128 gain format), to allow playback of several tracks or albums at a similar loudness level. r128gain can also be used as a Python module from other Python projects to scan and/or tag audio files.

This is beta software, please test and report bugs.

Features

Supports all common audio file formats (MP3, AAC, Vorbis, Opus, FLAC, WavPack...) and tag formats (ID3, Vorbis comments, MP4, APEv2...)
Writes tags compatible with music players reading track/album gain metadata
Supports new R128_XXX_GAIN tag format for Opus files (very few scanners write this tag, although it is defined in the Opus standard)
Supports writing gain to the Opus output gain header (experimental)
Uses threading to optimally use processor cores resulting in very fast processing

Installation

r128gain requires Python >= 3.6 and FFmpeg >= 2.8.

Standalone Windows executable

Windows users can download a standalone binary which does not require Python, and bundles FFmpeg.

Arch Linux

Arch Linux users can install the r128gain AUR package.

From PyPI (with PIP)

Install r128gain using pip: pip3 install r128gain

From source

If you don't already have it, install setuptools for Python 3
Clone this repository: git clone https://github.com/desbma/r128gain
Install r128gain: python3 setup.py install

Command line usage

Run r128gain -h to get full command line reference.

Examples

Scan a single file and display its loudness information: r128gain -d an_audio_file.mp3
Scan & tag a single file: r128gain an_audio_file.mp3
Scan & tag all audio files in music_directory and all its subdirectories: r128gain -r music_directory
Scan & tag all audio files in music_directory and all its subdirectories, and add album gain tags (files contained in each directory are considered as part of the same album): r128gain -r -a music_directory

r128gain's Issues

AttributeError module 'collections' has no attribute 'Iterable'

I just install r128gain on fedora-35, added all dependencies and ran into this error.

Failed to analyze file './some_file.flac': AttributeError module 'collections' has no attribute 'Iterable'

According to https://stackoverflow.com/questions/53978542/how-to-use-collections-abc-from-both-python-3-8-and-python-2-7/53978543#53978543 something has been deprecated somewhere.

opus replaygain vs other replaygain loudness

If I run this on my library that is partly opus and partly m4a, it seems like it will tag the files with different base loudnesses. This is bad if I want to skip from an opus track to an m4a track. If this true can we get an option that makes the entire library have the same loudness?

Option to remove lowercased similar tags

Hi.

Thanks a lot for a very nice tool!! Took me quite a while to find one that supported as many formats as this - good job!

Now I've used it on quite some files, and some of them have incorrect tags in lowercase like:

replaygain track gain           : -7.00 dB
replaygain track peak           : 0.811597
replaygain originator code      : 011011000000

It would be nice to have an option of removing those to ensure players don't accidentally use the wrong one (and it feels cleaner).

Is that something you'd consider implementing?

Add REPLAYGAIN_REFERENCE_LOUDNESS tag

Could I persuade you to add a "REPLAYGAIN_REFERENCE_LOUDNESS" tag like "metaflac --add-replay-gain" does?

This might come in handy for mixed environments that support it (like mine, having old media tagged using "REPLAYGAIN_REFERENCE_LOUDNESS=89 dB" and newer media using a -23 LUFS target, like "REPLAYGAIN_REFERENCE_LOUDNESS=-23 LUFS").

Commandline arg to switch between "RGv2", "ebur128" and "atsc" modes?

For mixed environments (like mine, old media being "replaygained" with v1 algorithm at 89 dB target, and newer media using the EBU R128/BS.1770 standard with -23 LUFS target and gating), it might just be great if we had a means of easily switching the intended target loudness, mode, and units.

For compatibility with older ReplayGain, r128gain could/should be as ist is—following the EBU R128 recommendation but with a differnt target of -18 LUFS (specified in old "dB" tag values).

Then again, some of us already produce/tag for more modern standards like:

EBU R128/BS.1770-2/-3/-4:
Target -23 LUFS, with gating, "LU"/"LUFS" units

"Varied" EBU R128, i.e. different target loudness, for example:
Target -18 LUFS, with gating, "LU"/"LUFS" units (instead of "dB")

ATSC A/85:
Target -24 LUFS, no gating, "LU"/"LUFS" units

There are actually programs that can handle stuff like that, like IDJC, Audacious, my soon-to-be-released version 0.4.5 of ices. IDJC even allows to set a different pregain for files tagged using "LU/LUFS" units.

So it’s be just great if we could specify on the commandline:
– the desired target loudness (like -16/-18/-23/-24 LUFS)
– and/or a mode like ebur128, rgv2, atsc (does ffmpeg handle "gating/no gating" or ATSC A/85?)
– the desired units for the tags (LU/LUFS vs. dB)

If all this sounds too complicated, it might be easier and less error-prone for the majority of users to just select between two "modes", ReplayGainv2 being the default, maybe like this:

r128gain …
—or—
r128gain --mode=rgv2 …
would use a target of -18 LUFS, gating, and "dB" units (as is)

r128gain --mode=ebur128 …
would use a target of -23 LUFS, gating, and "LU"/"LUFS" units (new)

maybe even (if ffmpeg handles that)
r128gain --mode=atsc …
would use a target of -24 LUFS, no gating, and "LU"/"LUFS" units (new but probably not often needed)

For these cases, it might be advisable to also store the REPLAYGAIN_REFERENCE_LOUDNESS tag (see my other issue #13).

Otherwise, thanks for your efforts to bring us a very usable tool!

Hey,
I have another corrupt file and maybe we can catch the exception it throws:

Unfortunately the tagging of the album fails with this one corrupt file.

existing tags not found

As a first test I checked if a tagged file was properly detected. It was not and ended up with these tags:

% metaflac --export-tags-to=- *1* | grep REPLAY
REPLAYGAIN_ALGORITHM=BS.1770
REPLAYGAIN_REFERENCE_LOUDNESS=-23.0 LUFS
REPLAYGAIN_ALBUM_GAIN=-14.2 LU

REPLAYGAIN_ALBUM_GAIN=-14.2 LU
REPLAYGAIN_TRACK_GAIN=-5.00 dB
REPLAYGAIN_TRACK_PEAK=0.99475100

After removing all tags with metaflac --remove-tag='REPLAYGAIN_ALBUM_GAIN' --remove-tag='REPLAYGAIN_TRACK_PEAK' --remove-tag='REPLAYGAIN_ALGORITHM' --remove-tag='REPLAYGAIN_TRACK_GAIN' --remove-tag='REPLAYGAIN_REFERENCE_LOUDNESS' *flac
and tagging again I got

metaflac --export-tags-to=- *2* |grep REPLAY

REPLAYGAIN_TRACK_PEAK=0.99630700
REPLAYGAIN_ALBUM_GAIN=-9.20 dB
REPLAYGAIN_ALBUM_PEAK=0.99996900

Looks like the existing tag detection is not entirely perfect.

"Failed to analyze files" for opus format in 0.8.0+

It appears something in r128gain's opus handling has broken between release 0.7.1 and the latest. For example the command r128gain -r -a -o . previously ran without error on a directory of .opus files (freshly written by ffmpeg+libopus) in 0.7.1, but on a fresh install I see the following:

Pinning my local install to r128gain==0.7.1 is a workaround.

New release?

The last release (1.0.6) was over a year ago and there have been quite a few changes since then. Perhaps it would be a good time to create a new release?

High memory usage when running r128gain against mp3 album

I've been on the fence about reporting this one as the answer might be "quit trying to run r128gain on a Raspberry Pi". But since the behaviour varies by the content being analyzed I'll go ahead and report it.

This is for the following setup:

A recent build of ffmpeg's master branch with --enable-libopus
r128gain 0.9.3
Raspberry Pi 3 (4 cores, 747MB usable RAM)
Copies of the Smashing Pumpkins fine "Mellon Collie & the Infinite Sadness" double album, 28 tracks freshly encoded to opus/mp3 with ffmpeg
USB-attached external disk for media storage & swap space

opus files

I run r128gain -r -a -o --ffmpeg-path=/usr/local/bin/ffmpeg --dry-run smash_opus. Memory usage is very low. Analysis takes about 12 minutes and r128gain completes successfully.

mp3 files

I run r128gain -r -a -o --ffmpeg-path=/usr/local/bin/ffmpeg --dry-run smash_mp3. Then memory usage gets too high and it grinds to a halt, eventually failing with an error.

Some things I have tried:

Limiting r128gain to a single thread - still crashes, just takes longer
Giving the system a lot of swap space - I've seen memory usage as high as 3GB before ffmpeg is oomkilled
Using an old (2017) build of ffmpeg I had lying around - analysis of individual files ("Analyzing loudness of file...") completes fine but r128gain breaks at the next stage with errors like Failed to analyze file 'smash_mp3/210 - We Only Come Out at Night.flac.mp3': CalledProcessError Command '['/usr/bin/ffmpeg', '-hide_banner', '-nostats', '-threads:0', '1', '-i', 'smash_mp3/210 - We Only Come Out at Night.flac.mp3', '-filter_threads', '1', '-map', 'a', '-filter:a', 'aformat=sample_fmts=s16,replaygain,ebur128=framelog=verbose', '-f', 'null', '/dev/null']' returned non-zero exit status 1, one per input file. Memory usage remains low and it fails immediately so this is probably an unrelated issue.
Using the OS (Debian GNU/Linux 9.8)'s default ffmpeg - as above

Here's some detailed output:

Peak tag doesn't conform to RG or ITU standards

First, thanks for this awesome tool.

I was surprised to see r128gain's peak tags show values higher than I expected, with some above 1.0 for lossless files, which seemed impossible. After doing some reading, I understand that this is the "true peak," or an estimation of where the peak would be after digital to analog conversion.

But in the ReplayGain 2.0 spec, peak amplitude reflects sample peak:

For uncompressed files simply, scanners store the maximum absolute sample value held in the file on any channel for positive or negative excursion. The single sample value should be converted to a floating-point representation, such that digital full scale is equivalent to a value of 1.0.

The ITU BS.1770-4 spec does advocate using true peak, but in decibels:

Meters that follow these guidelines, and that use an oversampled sampling rate of at least 192 kHz, should indicate the result in the units of dB TP, having converted the result to a logarithmic scale. This can be achieved by calculating “20log[10]” of the attenuated, oversampled, filtered, absolute value, then adding 12.04dB. The “dB TP” Designation signifies decibels relative to 100% full scale, true-peak measurement.

So instead of replaygain_album_peak=1.25892541, we would expect something like replaygain_album_peak=2.0 dB TP.

To be honest, the more I think about this, the more your behavior seems like the best combination of backwards compatibility and usefulness, but it does seem surprising and technically violate RGv2. Have you considered raising this with the people drafting the RGv2 spec and documenting the divergence in the meantime?

Thanks again for the software.

feature request: show existing replaygain tags

Hi there,

A feature request:

Would you consider adding an option to display existing replaygain tags for all supported audiofiles?

Thanks!

Feature request: Option to set custom target loudness

r128gain seems to target -18 LUFS, which is a good default in my opinion, but I would like to be able to change it.

Incorrect loudness with true peak above 0dBTP

I was testing r128gain with I Won the Loudness War by Dan Worrall, which has an integrated loudness of +2.3 LUFS. However, it is calculated as +1.9 LUFS when using r128gain.

I believe this is because r128gain tells ffmpeg to resample to 48kHz signed 16 bit stereo. The original audio is 44.1kHz and clips during resampling, reducing the maximum loudness.

This could be solved by removing the resample, though I am unsure what other effects that would have. Alternatively, the intermediate format could be switched to float. I have been able to get correct results with both methods.

aac louder mp3

I play the files with mpd and the tagged aac files are louder than the tagged mp3 files

Discrepancy between different tools

While I was looking for a suitable tool for Linux, I made a small comparison with 4 flac/opus files. This resulted in some very different values, which I would like to share here. Could it be that I've overlooked something?

Argument list too long

When I execute processing with such code:

source = glob.glob(f"{source}/*.mp3")
r128gain.process(source, album_gain=True, skip_tagged=True)

I have this error:

r128gain:Failed to analyze files 'song1.mp3','song2.mp3',...,'song6000.mp3': OSError [Errno 7] Argument list too long: 'ffmpeg'

I execute this command on directory that contains about 6000 mp3 tracks.

opus: sample peak only diplays a minus sign

When tagging an opus audo file( ogg container) the sample peak only shows a minus. The tag is fine however.

[mrgeorgen@mrgPC ~/Downloads]$ r128gain The_Weeknd-Save_Your_Tears.opus 
Analyzing loudness of file 'The_Weeknd-Save_Your_Tears.opus'... 
File 'The_Weeknd-Save_Your_Tears.opus': loudness = -7.9 LUFS, sample peak = - 
Tagging file 'The_Weeknd-Save_Your_Tears.opus'

I can upload the file, if you like

Is there a way to get a + sign for positive values, when using Ffmpeg to adjust gain it doesn't work without them.

For example, using "ffmpeg -i input.mp4 -c:v copy -af volume=replaygain=track output.mp4" if the track gain is 31.43, as it comes out of r128gain, nothing happens, whereas, if I open up the file in Mp3tag etc. and add in a + sign in front of the 31.43 (+31.43), it then works.

Opus: please support setting the header's output gain from album gain

The experimental option --opus-output-gain currently assigns track gain to the header output gain. However, album gain is usually a better normalization mode. For this reason, Opus developers used to recommend setting the header output gain to album gain. As a note, for this reason, foobar2000 sets it to album gain by default, and so does opusenc when converting REPLAYGAIN tags from FLAC.

Therefore, I would like to kindly request an option to set the header output gain to album gain instead of track gain, and perhaps even ask you to consider making this the default behavior.

problem with handling some tta files

http://sss.chaoslab.ru/08%20-%20Pittsburgh%20Symphony%20Orchestra;%20Manfred%20Honeck,%20music%20direct%20-%20Allegro%20con%20brio.dff.tta.tta

sample of not handled file.

A few enhancements?

r128gain has been very useful in analysing and adding r128 loudness tags to my music, however, there are a few additional capabilities I think would be useful for consideration:

add album dynamic range score calculated using R128
add option to output summarised data per folder only: Album loudness, peak, dynamic range
add ability to format data in CSV or other delimited format readily capable of import into a table

Clarification: order of scanned tracks in album dir non-deterministic?

Hello, I was wondering if the scan order of track files made a difference when calculating album gain? I noticed that when I ran r128gain --recursive --album-gain album_dir/ a couple of times, the scanning order of the track files changed between runs in a non-deterministic fashion, but the resulting album gain appeared to remain the same.

Support for Opus format

I have here a ogg/oga file using following codec (according to VLC):

Opus Audio / Stereo / 48000 Hz / 32 bits (per Sample)

When I try to tag this file by using r128gain it starts and then immediately exists silently - there is no error, no warning or any other message/hint printed.

Can you please add or fix support for the opus format?

mka container support

please implement mka container support.

Different loudness for OPUS and MP3 files encoded from the same FLAC file.

Hello. First of all thanks for making this software. I use it a lot and love it. :)

I am not sure if this is worth reporting but thought I'd ask anyway. This is the first time I have noticed something like this.

I am using this small script:

#!/usr/bin/env sh

ffmpeg -i ./electric_feel.flac -b:a 320k ./electric_feel.opus
ffmpeg -i ./electric_feel.flac -b:a 0 ./electric_feel.mp3
r128gain ./electric_feel.opus ./electric_feel.mp3

The resultant files are recognised to have different loudnesses.

Analyzing loudness of file './electric_feel.opus'...
Analyzing loudness of file './electric_feel.mp3'...
File './electric_feel.opus': loudness = -7.4 LUFS, sample peak = -
File './electric_feel.mp3': loudness = -7.8 LUFS, sample peak = 0.0 dBFS
Tagging file './electric_feel.opus'
Tagging file './electric_feel.mp3'

I think the difference is miniscule but on mpd I have set the preamp for replaygain tagged files to +8 because of which the OPUS file has noticeable distortion but the MP3 file seems fine.

I can provide electric_feel.flac if needed. Please feel free to close if this is a non-issue.

Thanks again.

Add an option to preserve file timestamps

Since some tools determine the time a file was added from the file timestamps it would be nice to have an option to preserve those.

If you're willing to implement this, I could give it a go and send you a pull request.

ReplayGain values too high for surround audio, often causing clipping

I noticed that r128gain does calculate ReplayGain for 5.1 and 7.1 surround files, but in my tests the gain values applied to 5.1 surround files were always over 7 dB higher than the file that was downmixed to stereo before running r128gain on it, which was normally high enough to cause clipping on multiple channels when applied.
I don't know how the gain values are currently calculated for surround audio, but I think a simple solution would be to just downmix the stream with ffmpeg -ac 2 for the gain calculations, and do the peak calculations separately without downmixing.

Different values to previous version?

Hi>
I have two or three questions.

I used r128gain-win32 to generate ReplayGain tags on an MP3 file already tagged in Winamp (5.8) to test what would happen.

I'll copy the extended tags here, some old, some newly generated:

REPLAYGAIN_ALBUM_GAIN -5.41 dB
REPLAYGAIN_ALBUM_PEAK 1.014365435
REPLAYGAIN_TRACK_GAIN -4.40 dB
REPLAYGAIN_TRACK_GAIN -5.26 dB
REPLAYGAIN_TRACK_PEAK 0.996887
REPLAYGAIN_TRACK_PEAK 0.996883988

Track gain -4.40 dB and track peak 0.996887 were added by r128gain.

I can remove tags on all MP3s -- I have many -- and it takes about 2 seconds, so that is not an issue. I'm wondering though, why does r128gain calculate a different gain and peak value?

Winamp: -5.26;
r128gain: -4.40
-- a pretty big difference.

I assume it has to do with ReplayGain version 2 versus version 1 that I believe Winamp still uses. Maybe I'm wrong. Winamp's documentation makes no mention of ReplayGain versions.

My second question>

According to the ReplayGain documentation, gain is applied by players that support ReplayGain by multiplying each sample value by a constant. The formula "ten raised to the power of one-twentieth of replay gain". For -5.26 dB, 0.54575786109127092251134492267094. For -4.4 dB, 0.60255958607435774697130296573509. I'm interested in the formula. (I sometimes I want to normalize WAV files that were encoded to MP3.) Does the r128gain-calculated track gain follow the same formula "ten raised to the power of one-twentieth of replay gain", applying it to every sample in a track to attenuate or increase replay gain?

Last but not least>

Can you outline why ReplayGain version 2 is better than version 1?

I look forward to a reply. I hope your reply can be soon, because I'm postponing switching from Winamp to r128gain.

Thanks.

Best regards,
Tom

Don't ignore files provided on the command-line in recursive mode

Thanks for the fantastic tool!

One little issue:

❯ r128gain -r --skip-tagged Alles\ tanzt\ _\ YADA\ Worship\ _\ Piano\ Tutorial\ \&\ Mainstage\ Patch.mp4
❯ r128gain --skip-tagged Alles\ tanzt\ _\ YADA\ Worship\ _\ Piano\ Tutorial\ \&\ Mainstage\ Patch.mp4
File 'Alles tanzt _ YADA Worship _ Piano Tutorial & Mainstage Patch.mp4' already has a track gain tag, skipping track gain scan
File 'Alles tanzt _ YADA Worship _ Piano Tutorial & Mainstage Patch.mp4': loudness = SKIPPED, sample peak = SKIPPED

I would expect it to also process provided files in recursive mode, like standard tools such as cp and mv.

Return code should report scan errors even if they are not fatal

Results shown in dbFS and not in LUFS

When running r128gain via the command line on a single file, the following text is outputted:

Analyzing loudness of file 'path/to/music.mp3'...
File 'path/to/music.mp3': loudness = -9.8 dbFS, peak = 0.6 dbFS

Units of loudness and peak are given in dbFS, not in LUFS. Is this the expected behavior, or have the units been mixed up?
If dbFS is the intended unit, it should read "dBFS".

iTMF meaning atom should probably not be uppercase

MP4/M4A tags are encoded under the COM.APPLE.ITUNES meaning by r128gain, but cmus only looks for com.apple.iTunes (case sensitive). I don't know if this is cmus's fault, but either way r128gain should probably be using the typical capitalization.

No pause/resume for larger collections

Hey there!
Thanks for this great piece of software... it really is cool, and works well.
Here is the situation, though... The collection it's chewing through now is about 400gb mp3... (About 93,000 songs in total)
As it's the first time this fine utility is running, I want to to obliterate any old replaygain tags.
The collection is ordered by artist, and there are 11,000 of those.
So, what I have done is to make a list of the subdirectories, and a small script that runs this fine utility on each of them.
This is easily achieved by ls -rt > Somefile.txt

The script is then run in the root directory of the collection, and supplied the text as input. It's attached here, and I give the devs full permission to use it in any way they see fit, and claim no copyright on it whatsoever.
Replay_Gain.zip

This script can be interrupted, and re-started at a later date. It will re-do the directory it was busy with when it was interrupted, providing a nice pause/resume functionality that survives reboots.

Display summary in recursive mode

a little bit like tree, something like: "Found X tracks in Y directories, updated tags for N of them" - this would help me to verify its work

Feature request: only treat those files as one album that also have identical album tags

Currently, enabling album gain will treat any (supported) audio files in one folder as one album. Which is problematic if tracks from multiple albums are in one folder. Only in the case of mistagged files, the current behavior is preferable. In my case, track collection of countless albums in one folder, album tag awareness would be very useful.
I think that ideally, album tag awareness should be the default, with the option to disable it.
In the special case of no album tag I would prefer them to not be bundled to one album for album gain calculation by default.
